Description Figure 2. Light microscopy of Neoechiniscoides aski. A–C, images of live, moving specimens.A, ventral view of a live adult female, showing the anal system with lateral wings. In live animals, the conspicuous anal complex moves from side to side when the animal walks/runs. Scale bar: 50 μm. B, dorsal view of live adult female used for DNA extraction (28S GenBank accession number KX363645; COI GenBank accession number KX363656). Note the eight to nine mature oocytes. Scale bar: 50 μm. C, dorsal view of live adult male. Scale bar: 50 μm. D, holotype of N. aski (female). Scale bar: 50 μm. E, paratypic allotype of N. aski (male). Scale bar: 50 μm. F, ventrocaudal view of holotypic female showing anal system and the gonopore, which is raised on an elevation (note that seminal receptacles are lacking). Scale bar: 20 μm. G, ventral view of paratypic
